Specific embodiment
Below with reference to annexed drawings description headrest tilt adjustment module in accordance with an exemplary embodiment of the invention.
Fig. 1 is the view for showing the headrest tilt adjustment module of an embodiment of the invention before operation, Fig. 2
It is the view for showing the headrest tilt adjustment module of an embodiment of the invention after the activation.
The headrest tilt adjustment module 10 for being installed on headrest of an embodiment of the invention includes：Base portion
100th, movable carriage 200, head support board 300 and connecting rod 400；Wherein, base portion 100 is supported in headrest；Movable carriage 200
It is attached to base portion 100 to move forward relative to base portion 100；One end of head support board 300 be attached to it is described can
Movable support bracket 200 is can turn forward；Two ends of connecting rod 400 are respectively coupled to the base portion 100 and the head
Fagging 300 so that when the movable carriage 200 is moved at least one end of the connecting rod in the base portion 100 or
Slide along predefined paths in head support board 300 described in person, so that the head support board 300 inclines along the predefined paths
Tiltedly.
Specifically, tilt adjustment module 10 of resting the head on is arranged in headrest, and wherein head restraint support is downwardly projected to fasten
To backrest.That is, headrest tilt adjustment module 10 is arranged in headrest, so that the head with the head contact of passenger
Pillow front shroud is located at the front of head support board 300.
Base portion 100 can be fixed to the inner frame for supporting headrest in headrest, support the inner frame of headrest have the back of the body
Plate, the backboard are attached to head restraint support.Obviously, base portion 100 can be arranged at diverse location.
Meanwhile, leading screw 110 and actuator 120 can be arranged at base portion 100, and the leading screw 110 is projected from substrate 100 forward
And movable carriage 200 is threaded io, the actuator 120 rotates leading screw 110 so that movable carriage 200 is in leading screw
Move forward on 110.
Actuator 120 can be arranged in base portion 100, and wherein rotary shaft can be by gear or other connection elements
Leading screw 110 is connected to, or rotary shaft can be directly connected to leading screw 110, thus transmit power.Alternatively, rotary shaft can be with
For leading screw 110 and project forwardly into base portion 100.
Additionally, leading screw 110 can be formed in base portion 100 through the first through hole (not providing reference) of its protrusion.
Actuator 120 receives the actuating signal from specific operation switch or controller, and can be according to required squint angle
Made by rotating leading screw 110 movable carriage 200 before the front direction of base portion 100/be moved rearwards by.Additionally, the second through hole
(not shown) can be formed in movable carriage 200, and second through hole has screw thread in inner peripheral surface to be threadedly coupled
It is threadedly coupled to leading screw 100, and allows leading screw 110 as which rotates and move.
Head support board 300 is the plate for supporting head of passenger and front side and head contact, the head support board
300 lower end can be hinged to movable carriage 200 and upper end is rotated around lower end.Additionally, head support board 300 can
To be attached to the both sides of the lower end of movable carriage 200, so as to head support board only forwardly and rearwardly can rotate, and head
Portion's gripper shoe can by equably by the both sides of the load distribution of head of passenger to the lower end of movable carriage 200 stably
Support the head of passenger.As upper end rotates forward, thus surface can be carried out with head naturally according to the shape of head
Contact, so that improve the ride quality of passenger.
Plate protuberance 310 is formed at the top of head support board 300, and the plate protuberance is projected and the company of being attached to backward
One end of bar 400, slip slit 311 can be formed in plate protuberance 310, and the slip slit provides predefined paths, connecting rod
400 one end is attached to the predefined paths to enter line slip.Connecting rod protuberance (not providing reference) can the company of being formed at
One end of bar 400, the connecting rod protuberance are inserted into slip slit 311 and can move along slip slit 311.
Additionally, the other end of connecting rod 400 can rotatably be hinged to the bottom of base portion 100.
Additionally, connection protuberance 410 is formed between the two ends of connecting rod 400 to be attached to movable carriage 200, guide narrow
Groove 210 can at corresponding to the position for coupling protuberance 410, edge be longitudinally formed in movable carriage 200, couples protuberance
410 pass through guide slit and slide.
As shown in Fig. 2 when movable carriage 200 is moved forward, insert the connection protuberance 410 of guide slit 210 to
Front movement.In this process, as the other end of connecting rod 400 is hinged to base portion 100, thus connecting rod 400 rotates forward and joins
Connect protuberance 410 to move down along guide slit 210 by the rotation of connecting rod.As connecting rod 400 rotates forward, connecting rod
400 one end is slided along slip slit 311 and the upper end of squeeze bulb gripper shoe 300 forward, thus head support board 300 around
Lower end rotates, thus run-off the straight.
In order to one end of the connecting rod 400 when connecting rod 400 is rotated according to the forward movement of movable carriage 200 makes head
Fagging 300 rotates forward, and the sum of the first variable range A and the second variable range B can or ratio ginseng equal with reference distance C
Examine bigger apart from C, wherein the first variable range A is the one end from the rear side of head support board 300 to connecting rod 400 and slip slit
Binding site horizontal range, the second variable range B is one end and the slip slit 411 from connection protuberance 410 to connecting rod 400
Binding site horizontal range, reference distance C be from connection protuberance 410 to the front side of movable carriage 200 horizontal range.
Therefore, it is possible to adjust the first variable range A and the second variable range B at least one so that the first variable range A
Become bigger than reference distance C with the sum of the second variable range B, so as to set according to the displacement of movable carriage 200
Determine the angle of inclination of head support board 300.For example, as shown in Fig. 2 can be by forming slip slit along the line after obliquely
311 and the rotation due to connecting rod 400 is formed move down the forward movement point that component is converted into head support board 300
Amount, can the shifting according to movable carriage 200 by the position of setting connection protuberance 410 between the two ends of connecting rod 400
Dynamic distance is setting the degree of the change of the second variable range B.The other end of the connection protuberance the closer to connecting rod 400, second can
Displacement according to movable carriage 200 increased even more by change apart from B.
Connecting rod 400 can be separately positioned on the two ends of base portion 100 in couples, and plate protuberance 310 can also be arranged in pairs in
The both sides of the rear side of head support board 300, guide slit 210 can also be arranged on the two ends of movable carriage 200.According to this
The two ends of construction, the difference support base 100 of a pair of links 400 and head support board 300, and prevent when leading screw 110 rotates
Movable carriage 200 is rotated to the direction of rotation of leading screw 110 together with leading screw, therefore, it is possible to accurately control movable carriage
200 forward/backward movement.
According to the headrest tilt adjustment module with said structure, movement and the inclination angle of forward/backward can be carried out simultaneously
Adjust, therefore, it is possible to carry out tilt adjustment in the larger context.
Additionally, head support board 300 is inclined with the movement of movable carriage 200, without being provided for making
The inclined specific actuator of head support board 300, therefore, it is possible to reducing manufacturing cost and improving productivity ratio.
Although with reference to the specific embodiment description present invention being shown in the drawings, but it is clear that people in the art understands
In a variety of different ways the present invention can be changed and modified, without departing from the sheet limited by claims below
